ADJUSTABLE FIRE-NOZZLI] SUPPORT.

Application led February 18, 1922.

To UZZ whom t may concern Be it known that I. JACOB B. Bmw, a citizen of the United States, and resident of Atlantic City, county of Atlantic, State of New Jersey, have invented an Improvement in Adjustable Fire-Nozzle Supports, of which the following is a specication.

The object of my invention is to provide an adjustable lire nozzle support which may be quickly and securely attached to the window sill or frame, a door frame, post or other convenient place of attachment and provided with adjustable supporting means to which the nozzle is clamped or secured and by which the direction of the stream .from the nozzle may be varied as desired; and further, whereby a plurality of nozzles may be simultaneously supported and adjusted for directing a plurality of streams of water upon the fire so that they may be simultaneously directed upon one place or may be directed in widely divergent directions, as the character of the fire may dictate.

The object of my invention is further to provide an adjustable fire nozzle support of a character which, while permitting free adjustment of the nozzle during the throwing of the stream, will at the same time sustain all of the recoil or kick back, thereby relieving the reman or operator from all undue strain and danger on this account and during said time permitting his energies to be exercised in the manipulation of the nozzle for proper direction of the stream under conditions of the highest efiiciency with the minimum of danger.

My object is further to provide a fire nozzle supporting means which will permit the nozzle to be adjusted in all directions for properly directing the stream, and clamping it in desired adjustments and positions, whereby in case of great danger or intolerable atmospheric conditions, due to smoke or noxious fumes, the operator may temporarily leave the nozzle to seek safety or protection against the said conditions without interfering with the normal operation of the fire nozzle in properly directing the stream.

My object is also to provide an adjustable clamping means with a plurality of adjustable nozzle supports, whereby a single hose line may be siamesed into supplying water 'to the plurality of nozzles and thereby permitting a plurality oi' streams to be directed Serial No. 537,456.

with a minimum number of men to manipulate the nozzles. j

With the above and other objects in view, the-nature of which will be more Jfully understood from the description hereinafter, the invention consists in the novel construction of adjustable fire nozzle support, as hereinafter more fully described and dened in the claims.

Referring to the drawings: Fig. l is a side elevation of my improved fire nozzle support showing it in connection with a window sill (in section); Fig. 2 is a front elevation of my improved adjustable re nozzle support; Fig. 3 is a top view of my improved fire nozzle support with the upper nozzle clamp removed and showing the device attached to the vertical frame of a door or post; Fig. l is a perspective view ot' the body casting to which the various parts of the device are adjustably secured; Fig. 5 is a perspective view of the several brace bars removed 'from the apparatus but retaining their relative positions; and Fig. 6 is a side view of one of the adjustable yokes for the nozzle clamps.

2 is the body frame, the shape of which will be best understood by reference to Fig. 4:. This body frame is provided with a vertical hole 23 for receiving the journal pin 30 of the upper yoke 26, in which is pivoted the U-shaped nozzle clamp 27, and in which the nozzle 50 may be clamped by straps 29, as will be clearly understood by reference to Figs. l and 2. As shown, the U-shaped nozzle clamp 27 is pivoted on a transverse axis` as indicated at 28, so that the nozzle 50 may be oscillated in a vertical plane about the said transverse axis for directing the stream at different elevations or depressions. The adjustment of the nozzle clamp 27 may be fixed, if desired, by means of the link 31a hinged at one end to the yoke 26 and adjustably clamped at 32a to the nozzle clamp, as fully shown in Fig. l.

The body part 2 is also provided with horizontal holes 24 and 25, respectively, at opposite sides of the vertical hole 23, said holes respectively supporting two additional clamping means, one of which comprises a yoke 31 having the journal pin 32 j ournaled in the hole 24, said yoke provided with a nozzle clamp 33 hinged to the yoke on a vertical axis indicated at 311-, and the other ci which comprises the yoke 35 having the pin 36 journaled in the hole 25 of the body and said yoke provided with a nozzle clamp 37 pivoted-to the yoke on a vertical axis at 38, said yokes 31 and 35 being respectively arranged at opposite sides ot the body portion 2, and at a lower level than the iirst mentioned yoke 26. Furthermore, the yoke 26 is adjustable about a vertical axis, whereas the yokes 31 and 35 are adjustable about a. horizontal axis. Inall cases, however, the nozzle clamps, as well as the nozzles sup ported thereby, would have capacity tor universal adjustment.

The yokes and their pins may be held in position upon the lbody part 2 in any convenient manner, either by 'transverse pins "or preferably by the clamping screws 39 and 45, the former cooperating with the yokes 31 and 35, and the latter with the yoke 26, said clamping screws being used as set screws when desired to hold the yokes rigidly against oscillation; 4and preferably at all times engaging grooves in the journal pins of the said yokes, such as indicated at 32b in Fig. 6, and whereby the yokes are l held against disengagement with the body portion.

The body part 2 is supported upon two hinged frames 3 and 8, respectively joined to opposite ends oli the body by transverse bolts 5 and 10. The iframe 3 is formed by two downwardly extending bars 4, a, connected at their lower ends bya transverse plate 6 having inwardly directly clampingspikes 7. The trame 8 is similarly composed oit' two bars 9, 9, connected at the bottom by a transverse frame 11 through which a clamping` screw 12 is extended`r the outer end of said screw being provided with a hand wheel 13 and the inner end'provided with a socket head 14e having a gripping prong 15. The head 14 is connected with the end of the screw 12 in any suitable manner, whereby the latter may have freedom oi rotation without rotating the head 14C. To insure 'more stability in a transverse directi'o`nthe bars 4 of the frame 3 are bent to spread at the bottom so that the transverse plate G may be of considerable length and provide for a series of the prongs '7, whereas the bars 9 do not spread inasmuch as there is only a single prong 15 controlled by the `adjusting screw 12. As these frame 3 and 8 are hinged to the body 2 bythe transverse bolts 5 and 19, it is necessary that they be held in some manner to prevent them spreading apart or permitting an undesirable adjust# ment oli' the body upon them. il simple 'means for providing a rigid connection between the said frames 3 and 8 and the body 2 is shown and comprises the bars substantially as indicated in the drawing. Fig. 5,

19 and 18 having spacing tubes 21 to keep the bars apart, four oblique bars 17, two ot' which are joined to the bolt 18 and two to the bolt 19, s aidbars having their other ends crossing and bolted rigidly at 20 to the body lrame 2;'and also two bars 16a, each connected at one end to the bolt 19 and at its otherend to a transverse bolt 16b which eX- tends between the opposite members 9 9 of the frame 8 a considerable distance below the bolt 18. The bars 16a 'sustain the recoil or kick-back during the passage of water under high pressure through the `nozzle (Fig, l). In this manner, the bracing bars 17, 16, 17, form a triangular Astructure and positively hold each oit the trames 3 and 8 in rigid adjustment with respect to the body part 2. The bars 16 and '17, however, are provided with a plurality 'of holes which permit of varying their length intermediate ot the bolts 18, 19 and 20, and consequently providing means for spreading the frames 3 and 8 relatively to each other "at their lower ends, 'which give capacity to the clamping means for adjustment to larger or smaller objects in excess oi what might be provided lfor by the screw 12. I do not re-` strict myself to any articular character ot bracing between Vthe rames 3 and 8 andthe body ytrame 2; and it will be furthermore understood that in respect to capacity Vfor adjustment, it would suffice for one of the. frames 3 and 8 to be rigidly positioned with respect to the body 2 and have adjustable capacity with .respect to the remaining frame, if so desired.

Fig. 1 indicates the adaptability of my improved nozzle supporting means attached to the window sill i3 in position to play the stream upon a building across the street or upon the same building at a distant place. AIn other cases, the device would be clamped to the window sill in the opposite direction so as to play the stream into the building to sult the rods l12 may be fitted `to transverse holes 40 in the vbody casting 2 and .clamped therein by clamping screws '41, all ot which will be understood by rete-rence t'o Figs. 3 and 4.

Further advantages oft my improvednozzle supporting` means, in addition to those already referred to, including the .protection vagainst recoil or kickback when manipulating powerful streams of water and the provision for operating a plurality of nozzles by siamesing from a single hose, the apparatus may be utilized in those 'cases where streams from several engines are siamesed into a single hose lineto give a far more powerful stream both for carrying it through a greater distance and for obtaining greater force to break down obstruction when necessary, and utilize the same without undue strain upon the operators which `has heretofore been necessary in holding a nozzle directing a stream of such force.

It will also be understood that my improved nozzle supporting means is adapted for use' in connection with fire trucks or on a ladder truck in front of a burning structure to enable a plurality of streams to be directed into a building where immediate at* tachment to the building is not possible. Furthermore, the device permits the throwing of a plurality of streams, whereby a water curtain can be easily formed to prevent spreading of coniiagrations.

The parts 2, 3, 8, and the bracing structure comprising the bars 16 and 17 and 16a, when connected together as described in the drawing, constitute a rigid frame structure for the adjustable nozzle supporting devices which are secured thereto, the parts 3 and 8 forming opposite side or leg portions of said structure.

It will now be apparent that I have devised a novel and useful construction which embodies the features of advantage enumerated as desirable, and while I have in theV present instance shown and described the preferred embodiment thereof which has been found in practice to give satisfactory and reliable results, it is to be understood that I do not restrict myself to the details, as the same are susceptible of modification in various particulars without departing from the spirit or scope of the invention.

I-Iaving now described my invention, what I claim as new and desire to secure by Let-y ters Patent is l. In a device of the character stated, a body part having adjustable clamping means whereby it may be detachably clamped in position upon a window sill, door frame, or other object, combined with a plurality of adjustable nozzle supporting means adapted to be used simultaneously, said su porting means being separately pivoted tothe body part with capacity for being directed at different angles, whereby separate nozzles may be adjusted to concentrate the streams upon one spot or upon different portions of the coniiagration.
